Needs a little more QA

Written on Sep 26, 2021

I ordered the Hiperfire PDI for the MCX due to having an MPX. The first trigger I received had a hammer strike so hard it gave me a blood blister under my fingernail from pulling the trigger while installing. I have never felt a hammer strike that hard. Once I went to the range, the trigger doubled on the first pull. I fired about 30 rounds and it doubled almost every time. I took it apart and looked at the trigger and the disconnect had completely worn down. I called Hiperfire and customer service asked a few questions and I sent the trigger back and they sent me another within a week. I estimate the new trigger to be about 1/3 of the hammer strike of the last one and it seems to be holding up better.

Poor fit on mag release button

Written on Jul 28, 2019

I ordered the black version of this for a build I doing. I started trying to install the mag release button and found it was too large. I measured the existing button I had and it was .490 x .290 where the button with this kit was .514 x .310 which wouldn’t work. I don’t know if it was a manufacturing error or a design error, but I previously got a gen III version and it works great on another build I did with an identical Aero Precision lower.
